当变压器遇到绝缘故障或其他故障，导致变压器油温急剧升高，在即将发生爆裂或火灾危险时，控制系统确认收到电气故障信号、温度探测信号以及重瓦斯信号灯关键信号后，立即启动排油机构——排油泄压，随即，启动注氮系统，将充足的氮气源源不断地注入变压器内部，搅拌、冷却变压器油，使其油温降到闪电以下；同时大量的氮气充满整个变压器油箱，隔绝氧气，从而实现高效灭火。
When the transformer encounters insulation fault or other faults, resulting in a sharp increase in the temperature of transformer oil. When the explosion or fire danger is imminent, the control system confirms that it receives the electrical fault signal, temperature detection signal and the key signal of the heavy gas bingxisuan.07858.netmojusl.37ix.com.cnmojuldlc.37ix.com.cnpprkeli.71ix.com weixinghulu.07858.netzaozhi.07858.netsignal lamp, immediately starts the oil drainage and pressure relief mechanism, then starts the nitrogen injection system, and continuously injects sufficient nitrogen gas into the transformer. Inside the transformer, the transformer oil is stirred and cooled so that the oil temperature drops below lightning. At the same time, a large amount of nitrogen fills the entire transformer tank, isolating oxygen, so as to achieve efficient fire extinguishing.
